Games for dog on 'minimal exercise'

Our springer had a little mishap over the weekend and has ended up with a few staples in his leg and enforced low exercise regime for another week.

So apart from short walks and pootling around the garden we need to keep him amused, we normally get him to hunt around the house for toys and treats, he has enough toys, one or two that need thought to get treats, he loves taking the lids off bottles etc

Does anyone have any other good ideas to challenge him mentally... I've tried and he just can't grasp poker or domino's

How about airport security? Dog sits by door, stream of people go past with bags, one of the bags contains treats/toy. Dog has to indicate the correct bag to win...
Could be a gameshow for dogs in a parallel universe...

Gonna be a tad boring ( possibly) and suggest doing basic training exercises. Dogs like a Springers love completing tasks and pleasing you - I think he would love it and it obviously isn't too taxing! An hour of this each evening would probably do you both the world of good
Sit, roll over, give paw, fetch specific items from a few, turn to heel etcetc The list is endless!
Have fun whatever you up doing and it's only a week to go!

I never feed mine food in a bowl, it always get thrown over the grass in the garden, he spends ages finding every single biscuit, he loves hunting up and down for them and it keeps him occupied for far longer than it just being shoved under his nose.

How about putting one of his favourite toys in a cardboard box, tape it up, and let him destroy the box to get it out. This will keep my destructo-pup entertained for a good while. Can also do it with bits of cardboard layered around a treat in a pass-the-parcel stylee.
